Abstract
The present invention discloses a medium-high speed high-capacity hydraulic turbo-generator set thrust bearing. It includes thrust bearing seat, thrust head, thrust oil tank, oil-stopping pipe, oil cooler, support screw and thrust bearing insert. The mirror plate and thrust head are separately arranged, the combined position of thrust oil tank and oil tank cap is equipped with an oil-resisting rubber strip, in the thrust oil tank an oil-stabilizing plate is set, between the support screw and thrust bearing insert a tray is set, and the regulation bolt of support screw is locked by means of locking plate.
Description
Technical field
The present invention relates to a kind of dynamo bearing, particularly a kind of high speed large volume hydroelectric generating set thrust bearing.
Background technique
Thrust-bearing is one of the most key vitals of hydraulic turbine generator, it is most important to the convenience of the safety reliability of unit operation and Economy and installation and maintenance, the operation practice of domestic water turbine generator group shows: the accident that big-and-middle-sized hydraulic turbine generator causes because of thrust-bearing accounts for 55～70% of unit mechanical accident, bearing gets rid of oil, it is fixed that the greasy dirt that leakage of oil and mist of oil form covers generator, above the rotor coil, can reduce the dielectric strength of coil, hinder the normal heat radiation of winding, and mist of oil is dispersed into the operation factory building also can endanger the healthy of field personnel.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, provides a kind of and can overcome the thrust-bearing that hydraulic generator thrust bearing gets rid of oil, leakage of oil and reduces the mist of oil of unit generation, is applicable to high speed large capacity hydroelectric generator group.
Goal of the invention of the present invention is achieved through the following technical solutions: a kind of high speed large volume hydroelectric generating set thrust bearing, comprise thrust metal, thrust collar, thrust bearing oil sump, the retaining oil pipe, oil cooler, pillar screw, thrust bearing shoe, thrust metal is fixed on the upper spider, pillar screw is fixed on the thrust metal, pillar screw is supported thrust bearing shoe, thrust collar is fixed on the generator shaft by ring key, thrust bearing oil sump and retaining oil pipe constitute fuel reserve tank, thrust bearing oil sump covers with oil groove, it is characterized in that runner plate and thrust collar branch are arranged, avoid the mating face corrosion of thrust collar and runner plate, prevent unit axis generation deviation and cause the unit operation vibrations to strengthen, thrust bearing oil sump and oil groove lid commissure are provided with the oil-proof rubber bar, be provided with oil-stabilizing plate in the thrust bearing oil sump, thrust bearing oil sump be provided with outward sealing cover prevent the thrust bearing oil sump leakage of oil and inside and outside get rid of oil.
Be provided with pallet between pillar screw and the thrust bearing shoe, the adjusting bolt of pillar screw locks with lockplate, helps to improve the stability of unit operation.
The material of thrust collar is ZG20SiMn, and the material of runner plate is No. 45 forged steel, and the rigidity of thrust collar and runner plate is strong, produces periodic wavy distortion when avoiding moving and causes the contact corrosion on the mating face of thrust collar and runner plate.
Thrust bearing shoe is a plastic made tile, the plastic made tile friction factor is very little, abrasion loss is very little, the power of attrition is less, do not need the axle insulation, especially the withstand voltage temperature resistant capability of plastic made tile is stronger, there is the tile kilning problem hardly, even can cut off the water supply at cooler and move down, thereby effectively reduce the unit operation fault.
From top narration as can be seen, a kind of high speed large volume hydroelectric generating set thrust bearing provided by the invention, can effectively solve thrust-bearing and get rid of oil, leakage of oil problem, shake when reducing unit operation, improve operational reliability, Security and the stability of unit.
